 in importance to speed, come great carrying 

 capacity and great radius of action, both 

 dependent on bulk. 



Speed makes the Zeppelin practically 

 independent of adverse winds. But speed 

 is essential not to drive a Zeppelin obstin- 

 ately against the wind in a straight line

In this picture a Zeppelin is placed above the United States superdreadnought Texas. The 

 comparative sizes have been carefully maintained. The Texas has an over all length 

 of 573 feet, the latest Zeppelin is 670 feet long. But the battleship is more powerful
